Mechanisms of Climate Change Impacts

Mechanisms of Climate Change Impacts

When thinking about information on adaptation technologies as described in the previous page, if one is to accurately grasp the need for these technologies in the coastal zones of the Asia-Pacific region, it is important to understand the mechanisms of climate change impacts in those zones. The flow described below is envisioned as an overarching framework for that understanding.

FIND SERIES OF ADAPTATION STEPS

while adequately considering information that can be useful at the local level.

To begin with, "changes in climate factors" occur, such as air temperature rise, sea temperature rise, and sea level rise, followed by "primary impacts," such as flooding, inundation, coastal erosion, saltwater intrusion, and impacts on ecosystems. Next are the resulting "secondary impacts," such as impacts on agriculture and fisheries, and on land conservation. Finally, it is necessary to consider not only the primary and secondary impacts of climate change, but also the effects that arise from combinations of current environmental and societal factors. Based on impacts such as those mentioned above, the assumed impacts and technology needs are then compiled for each coastal type. Finally, is also important for national and local governments to consider the kinds of impacts climate change will have on future growth strategies and development plans.
